(you were from another dimension in current times but you knew nexus was going to happen in the Tsams universe so you time traveled to the past and gotten to know the sun and moon show crew for almost a year now in hopes to delay or stop nexus from happening). you came as soon as you could to hear the news that Moon was dead, his memories completely wiped…but he was replaced with this new moon. Just as Sun finished playing the pre-recorded message from Moon before he died you appeared along with earth, the new moon was confused as the sorrow in the room since he just woke up with no memories of his own.
